A fertilizer blend containing 10 wt. % to 90 wt. % of a first particulate fertilizer composition and 10 wt. % to 90 wt. % of a second particulate fertilizer composition is disclosed. In the fertilizer blend, the second particulate fertilizer composition can be blended with the first particulate fertilizer composition. The first particulate fertilizer composition can include a core containing a binder, a pH buffering agent, and an urease inhibitor, and a shell containing urea, where the shell covers at least a portion of an outer surface of the core.

The present invention relates to a method for encapsulating a compound selected from the group consisting of at least one active substance, at least one microorganism and mixtures thereof in an organic-inorganic hybrid material of 2:1 lamellar structure, said material having the following general formula I:
Na.sub.x[(Mg.sub.3)(Al.sub.x(RSi).sub.4−x)O.sub.8+x(OH).sub.2]  (I)
the method comprising:
a) sol-gel synthesis of the organic-inorganic hybrid material of 2:1 lamellar structure in the presence of the compound;
b) recovery of the compound encapsulated in the material of general formula I. It further relates to the compound encapsulated in an organic-inorganic hybrid material of 2:1 lamellar structure of general formula I, a composition comprising same and its use for fertilizing, feeding, stimulating growth and/or prophylaxis of plants and/or improvement of the physical, chemical and/or biological properties of the soil or of the culture substrate of plants.

An ammonia capture and recovery system comprises five process steps, including an ammonia removal step, an ammonia recovery step, a product granulation step, a granulated product wax-coating step, and a granulated product encapsulation step. These steps are modular in that multiple approaches are valid for each step if it meets the process requirements for the next influent. Also, a method of taking ammonia-containing wastewater and producing several water fractions (preferably of decreasing volume and increasing purity) and a time-release ammonium-containing fertilizer, resulting in a sustainable nitrogenous fertilizer product that reduces fertilizer use and subsequent nutrient runoff while being produced from wastewater and not fossil fuel or hydrogen sources.

The present invention relates to fertilizer particles encapsulated in modified chitosan and a method of obtaining them. The particles described in this invention allow a controlled, moderate, or gradual release of an active material from a reserve substrate to another medium, in order to increase the effectiveness of the active material by prolonging its action over time. This invention is characterized in that the active components of said formulations are capable of causing a synergistic effect, considerably increasing the growth and development of plants.

Described herein are blends of carbohydrate-based polymeric materials with other polymeric materials, where the carbohydrate-based polymeric material is intimately blended with the other polymeric material, so as to exhibit very small particles sizes (e.g., less than 2 μm, or less than 1 μm) for the carbohydrate-based polymeric material in the matrix of the other polymeric material. Such intimate dispersion of very small particles provides for far more of the particles dispersed more evenly throughout the matrix of the other polymeric material, which may enhance various performance characteristics of the blended composite material, and provide for more consistent achievement of such characteristics, from batch to batch. Methods of producing articles from such blends exhibiting such small particles and excellent dispersion are also disclosed. While suitable for use in a wide variety of fields, examples may include for the coating of paper cups, and as a capsule material for sustained release fertilizer.
